Om mig

Forskare och statistiker på Institutionen för Medicinsk Epidemiologi och Biostatistik (http://ki.se/meb) och Svenska Tvillingregistret (http://ki.se/forskning/svenska-tvillingregistret).

Forskningsbeskrivning

Registerbaserad forskning i Borderline personlighetsstörning
Jag leder en bredare undersökning av Borderline personlighetsstörning, dess orsaker, komorbiditeter, konsekvenser, och farmakologiskt behandling. Vi nyttjar de omfattande populationsregistren i Sverige för att undersöka associationer och hypoteser i den största gruppen med Borderline personlighetsstörningsdiagnos som någonsin studerats.

Psykiatrisk epidemiologi
Jag är inblandad i undersökningar av bland annat ADHD, autism, och ångest i Henrik Larsson (https://ki.se/people/henlar) och Paul Lichtensteins (https://ki.se/people/paulic) forskargrupper. Jag samarbetar med forskargrupper inom psykiatrisk epidemiologi på Institutionen för Medicinsk Epidemiologi och Biostatistik i en grupp som heter PsychEpi.

Undervisning

Jag är kursansvarig för kursen "Design and Analysis of Twin- and Family-based studies" som ges inom ramen för doktorandprogrammet i epidemiologi.
